Today we had to patch a class function in production. Monkey patching can become tricky if reference are kept at several place like pointer in C and C++.Here is a simple example on how to make sure all references will use the new definition.

class Foo: def f(self): print "default f"

def newf(self): print "newf"

Foo.f.im_func.func_code = newf.func_code

This is another reason why interpreter language like python are so powerful.
